ANTHONY ISKE, OF LANCASTER, PENNSYLVANIA, ASSIGNOR TO J. WALTER MILLER,OF SAME PLACE.

DOOR-BELL.

SPECIFICATION forming part of Letters Patent No. 488,244, dated December20, 1892.

Application filed January 28, 1892. derial No. 419,500. (No model.)

To all whom it may concern:

Be it known that I, ANTHONY ISKE, a citizen of the United States,residing at Lancaster, in the county of Lancaster and State ofPennsylvania, haveinvented certain new and useful Improvements inDoor-Bells; andI do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which no it appertains to make and use the same.

This invention relates to door-bells operated by a sliding bar; and itconsists chiefly in the combination of a sliding-bar having a zigzag ortortuous path formed therein preferably by slotting it with abell-hammer or alarm-sounding device the tail of which engages the slotin the said bar.

It also consists in the combination of a retracting spring with the saidbar, upon which it acts, the hammer and the bell, so that the zigzag ortortuous path in the said bar will cause the hammer to give two seriesof strokes, the first when the said bar is drawn out by the bell-pull,the second when the said spring draws the said bar back again.

The said invention finally consists in certain additional details ofconstruction hereinafter more particularly set forth and claimed.

In the accompanying drawings Figure 1 0 represents a plan View of adoor-bell constructed in accordance with my invention, the gongbeingindicated by dotted lines: Fig. 2 represents a vertical section of thesame on the line a:0c of Fig. 1; Fig. 3 represents a view 3 5 similar toFig. 2, but of a part of the devices only, showing another form ofhammer; Fig.

4 represents a perspective detail view of the slidingbarand hammerbelonging to the construction shown in Fig. 3.

In the said drawings, A designates the flat base ofmy bell, which baseis preferably metallic and pear-shaped it being also provided with a lowraised rim a, and with screw-holes a for fastening it to a door-frame orother 5 woodwork. At the neck of this pear-shaped base A, the side-wallsformed by this rim are connected by a cross-plate, forming a fiatarchedguideway A. A second guidewayA of similar form is raised in the middleof this base. Through these guideways a flat slid- 5o ing bar Breciprocates as hereinafter de scribed, the said rim being cut away at afor allowing the rearward protrusion of the said bar. The material ofthe said base is partly cut away at A to lessen the friction against theunder side of the said bar but enough is left to complete the guidingunderneath. On the guideway A in the center of the said base, a post orstandard A is raised, this being provided in its top with ascrew-threaded 6o recess (0 to receive a screw 0, by which the gong O isfastened in its place in the usual manner. The edge of the said gong andthe top of the rim a leave only a very narrow open space between them;so that the interior devices are very well protected by these parts.

D designates, in Figs. 1 and 2, a bent hammer for striking the saidgong, formed of a wire which is wound about a raised stud e on the topof the guideway A a second stud f, taller than a, being bent over at thetop to hold the coiled part of the said wire in its place. The stud econstitutes the pivot on which the said hammer vibrates. The hammer-tailD constituting practically a stud, enters from above a zigzag slot orchannel B, which is formed longitudinally in the bar B. The bell-wire Eis attached to the forward end of said bar, and when the said wire ispulled the bar B, moving forward, causes the said hammer-tail to movefrom side to side in rapid vibration, each bend or angle of the pathchannel or slot B corresponding to one lateral motion of the said hammertail. 0f course each such motion of the latter is accompanied by astroke on the gong 0 when the said gong is in place. To retract the saidbar after the pull on the bell-wire E has ceased I employ a spring F,which is coiled about a stout stud F raised on the base A, at one sidethereof, one end of the said spring bearing against a fixed lug F of thesaid base, and the other end of the said spring being bent around a studB on the said bar at or near its lower end. Between the two studs F andB the spring, for greater strength and resiliency is wound into a helixor coil F Of course I do not confine myself rigidly to this peculiarconstruction of the spring as it may be largely varied. But I find it avery efficient form and easy and cheap to manu facture.

Instead of the bent Wire hammer above described, I sometimes, as inFigs. 3 and 4, make use of a hammer G, consisting of a straight rod,having the usual hammer head 9 and set into a long block G, which isconstructed with a central hole g receiving, and pivoted upon, a stoutstud G extending downward from the top of the guideway A. This block orstock G is also provided behind the said pivot-stud with a downwardlyextending stud or pin g which enters the path channel or slot B theoperation being otherwise as hereinafter described.

Of course a small bell may be mounted in place of the hammer-head, thegong being omitted. Also the path B may be raised on vided on its innerside with a stud G integral with the said guideway fitting into the saidhole g and serving as a pivot for the said hammer substantially as setforth.

In testimony whereof I affix my signature in presence of two witnesses.
